This patch provides the implementation of an AES-NI accelerated crypto PMD which is dependent on Intel's multi-buffer library, see the white paper "Fast Multi-buffer IPsec Implementations on Intel® Architecture Processors" This PMD supports AES_GCM authenticated encryption and authenticated decryption using 128-bit AES keys The patch also contains the related unit tests functions Signed-off-by: Declan Doherty <declan.doherty@intel.com> Signed-off-by: Pablo de Lara <pablo.de.lara.guarch@intel.com> Acked-by: John Griffin <john.griffin@intel.com>

AES-NI GCM Crypto Poll Mode Driver
|
|
============================================
|
|
|
|
|
|
The AES-NI GCM PMD (**librte_pmd_aesni_gcm**) provides poll mode crypto driver
|
|
support for utilizing Intel multi buffer library (see AES-NI Multi-buffer PMD documentation
|
|
to learn more about it, including installation).
|
|
|
|
The AES-NI GCM PMD has current only been tested on Fedora 21 64-bit with gcc.
|
|
|
|
Features
|
|
--------
|
|
|
|
AESNI GCM PMD has support for:
|
|
|
|
Cipher algorithms:
|
|
|
|
* RTE_CRYPTO_CIPHER_AES_GCM
|
|
|
|
Authentication algorithms:
|
|
|
|
* RTE_CRYPTO_AUTH_AES_GCM
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* Chained mbufs are not supported.
|
|
* Hash only is not supported.
|
|
* Cipher only is not supported.
|
|
* Only in-place is currently supported (destination address is the same as source address).
|
|
* Only supports session-oriented API implementation (session-less APIs are not supported).
|
|
* Not performance tuned.
|
|
|
|
The environmental variable
|
|
AESNI_MULTI_BUFFER_LIB_PATH must be exported with the path where you extracted
|
|
and built the multi buffer library and finally set
|
|
CONFIG_RTE_LIBRTE_PMD_AESNI_GCM=y in config/common_base.
